To find \( \mathrm{i}^{17} \), let's first recognize that \( \mathrm{i} \) is the imaginary unit, representing \( \sqrt{-1} \). The powers of \( \mathrm{i} \) cycle every four: \( \mathrm{i}^1 = \mathrm{i} \), \( \mathrm{i}^2 = -1 \), \( \mathrm{i}^3 = -\mathrm{i} \), and \( \mathrm{i}^4 = 1 \). For \( \mathrm{i}^{17} \), we can use the cycle by calculating \( 17 \mod 4 \), which gives us a remainder of 1. Thus, \( \mathrm{i}^{17} = \mathrm{i}^1 = \mathrm{i} \). So, the answer is \( \mathrm{i} \), which is option (3).
